                Improves the performance of managed applications by creating native images.
                Requires the .NET Framework 2.0 or newer to be installed on the target machine since
                it runs <html:a href="http://msdn2.microsoft.com/en-us/library/6t9t5wcf.aspx">NGen</html:a>.

                <xse:remarks>
                    Native images are files containing compiled processor-specific machine code, which
                    are installed into the native image cache on the local computer. The runtime
                    can use native images from the cache instead using the just-in-time (JIT)
                    compiler to compile the original assembly.
                    The native image custom actions are configured to ignore failures so that failing
                    to generate or remove a native image will not cause setup to fail and roll back.

                        The identifier for this NativeImage.

                        The identifier of the directory to use for locating dependent assemblies.
                        For DLL assemblies and assemblies installed to the Global Assembly Cache (GAC),
                        this attribute should be set to the directory of the application which loads this
                        assembly.  For EXE assemblies, this attribute does not need to be set because NGen
                        will use the directory of the assembly file by default.

                <xs:annotation>
                    <xs:documentation>
                        The identifier of the application which will load this assembly.
                        For DLL assemblies which are loaded via reflection, this attribute should
                        be set to indicate the application which will load this assembly.
                        The configuration of the application (usually specified via an exe.config file) will be used
                        to determine how to resolve dependencies for this assembly.
                        When a shared component is loaded at run time, using the Load method, the
                        application's configuration file determines the dependencies that are loaded
                        for the shared component — for example, the version of a dependency that is loaded.
                        This attribute gives guidance on which dependencies would be loaded at run time in order
                        to figure out which dependency assemblies will also need to have native images generated
                        (assuming the Dependency attribute is not set to "no").
                        This attribute cannot be set if the AssemblyApplication attribute is set on the parent
                        File element (please note that these attributes both refer to the same application
                        assembly but do very different things: specifiying File/@AssemblyApplication will force
                        an assembly to install to a private location next to the indicated application, whereas
                        this AssemblyApplication attribute will be used to help resolve dependent assemblies
                        while generating native images for this assembly).
